Download or read book The Use of Onboard Diagnostics to Reduce Emissions in Automobiles written by Alberto Perez (Jr.) and published by . This book was released on 2009 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emissions from automobiles are very harmful and include gases such as Carbon Dioxide, Nitrous Oxide, and Sulfur Dioxide. One of the main reasons OBD was created was to control emissions however it currently only monitors the status of the systems set in place to reduce emissions. The goal of this project is to use the OBD II system currently available in vehicles to monitor fuel emissions from many cars at different locations. By placing a small OBD II scanner and GPS receiver into a fleet of vehicles, emissions from these vehicles can be monitored and mapped out to show the different emissions levels on different roads. Although the plan is to develop a cheaper OBD II scanner and GPS unit to place on a few cars, an already existing scanner and GPS receiver has been used to begin collecting data for analysis, which will be discussed in this paper. The data has been useful to prove that road design and driver input impact the fuel consumption and emissions of a vehicle heavily.

Download or read book Evaluating Vehicle Emissions Inspection and Maintenance Programs written by National Research Council and published by National Academies Press. This book was released on 2001-11-16 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emissions inspection and maintenance (I/M) programs subject vehicles to periodic inspections of their emission control systems. Despite widespread use of these programs in air-quality management, policy makers and the public have found a number of problems associated with them. Prominent among these issues is the perception that emissions benefits and other impacts of I/M programs have not been evaluated adequately. Evaluating Vehicle Emissions Inspection and Maintenance Programs assesses the effectiveness of these programs for reducing mobile source emissions. In this report, the committee evaluates the differences in the characteristics of motor vehicle emissions in areas with and without I/M programs, identifies criteria and methodologies for their evaluation, and recommends improvements to the programs. Most useful of all, this book will help summarize the observed benefits of these programs and how they can be redirected in the future to increase their effectiveness.

The book will help new students develop diagnostic skills and help experienced technicians improve even further. This new edition is fully updated to the latest technological developments. Two new chapters have been added – On-board diagnostics and Oscilloscope diagnostics – and the coverage has been matched to the latest curricula of motor vehicle qualifications, including: IMI and C&G Technical Certificates and NVQs; Level 4 diagnostic units; BTEC National and Higher National qualifications from Edexcel; International Motor Vehicle qualifications such as C&G 3905; and ASE certification in the USA.
Download or read book Data Acquisition from HD Vehicles Using J1939 CAN Bus written by Richard Walter and published by SAE International. This book was released on 2016-07-14 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern vehicles have electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (or simply ‘controllers’) are networked together to share information, and output directly measured and calculated data to each other. This in-vehicle network is a data goldmine for improved maintenance, measuring vehicle performance and its subsystems, fleet management, warranty and legal issues, reliability, durability, and accident reconstruction. The focus of Data Acquisition from HD Vehicles Using J1939 CAN Bus is to guide the reader on how to acquire and correctly interpret data from the in-vehicle network of heavy-duty (HD) vehicles. The reader will learn how to convert messages to scaled engineering parameters, and how to determine the available parameters on HD vehicles, along with their accuracy and update rate. Written by two specialists in this field, Richard (Rick) P. Walter and Eric P. Walter, principals at HEM Data, located in the United States, the book provides a unique road map for the data acquisition user. The authors give a clear and concise description of the CAN protocol plus a review of all 19 parts of the SAE International J1939 standard family. Pertinent standards are illuminated with tables, graphs and examples. Practical applications covered are calculating fuel economy, duty cycle analysis, and capturing intermittent faults. A comparison is made of various diagnostic approaches including OBD-II, HD-OBD and World Wide Harmonized (WWH) OBD. Data Acquisition from HD Vehicles Using J1939 CAN Bus is a must-have reference for those interested to acquire data effectively from the SAE J1939 equipped vehicles.

Download or read book State and Federal Standards for Mobile Source Emissions written by National Research Council and published by National Academies Press. This book was released on 2006-06-15 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emissions from mobile sources contribute significantly to air pollution in the United States. Such sources include cars and light- and heavy-duty trucks; diesel-powered cranes, bulldozers, and tractors; and equipment such as lawnmowers that run on small gasoline engines. The role of state versus federal government in establishing mobile-source emissions standards is an important environmental management issue. With this in mind, Congress called on EPA to arrange an independent study of the practices and procedures by which California develops separate emissions standards from the federal government and other states choose to adopt the California standards. The report provides an assessment of the scientific and technical procedures used by states to develop or adopt different emissions standards and a comparison of those policies and practices with those used by EPA. It also considers the impacts of state emissions standards on various factors including compliance costs and emissions. The report concludes that, despite the substantial progress in reducing emissions from mobile sources nationwide, more needs to be done to attain federal air-quality standards in many parts of the country. Additionally, California should continue its pioneering role in setting emissions standards for cars, trucks, and off-road equipment.
